SWIVEL-SUPPORT FOR GRAlN-SPOUTSf SPECIFICATION forming part of LettersPatent No. 512,394, dated January 9, 1894. Application filed September27, 1892. Serial No. 447,027. (No model.)

To all whom it may concern:

Be it known that I, DIGHTON A. ROBINSON,

of Minneapolis, county of Hennepin, State of Minnesota, have inventedcertain new and useful Improvements in Swivel-Supports for Grain-spouts,of which the following is a specification.

My invention relates to means for pivotally supporting the upper end ofa grain spout, and in particular to such ,a support arranged inconnection with a track from which the same depends.

The object which I have in view, is to prevent the binding of one partof the spout upon the other, or its support whereby its movement isrendered easy.

The simplification of the swivel joint is a further object.

To this end my invention consists in general in the construction andcombination hereinafter described and particularly pointed out in theclaims, and will be more readily understood by reference to theaccompanying drawings, in' which Figure 1 is a side elevation of adeviceem bodying my invention, in which the track is shown in section. Fig. 2is a vertical section on the line 00-00 of Fig. 1. Fig. 3 is a sectionalview showing a modification.

As shown in the drawings, 2 represents a section of a circular, oblongor straight track upon which the lower part of the grain spout is to besupported. For this purpose I provide the loop hanger having the flatpart 3,

to which the grooved rollers 4 are secured by the bolts 5. These rollersare prevented from jumping the rail by the stud bolts 6, projecting fromthe sides of the loop underneath the rail. From this point down the endsof the strap are turned at right angles to the upper part thereof andthe ends split into the outwardly curved legs 7, which firmly hold thering 8 to which they are fastened by the short bolts 9. At quarters onthis ring are thestud bolts 10 projecting through the same to receivethe anti-friction rollers 11, which rollers project up into the annulargroove 12 on the overhanging part of the cast iron hop per end or cap 13of the main spout 14, fastenedto the lower end of the cap by rivets andthe rings 15. The expanded hopper top of this head is adapted to receivethe lower end of the upper section of the grain spout and from itsconical shape to make a tight joint therewith to prevent the scatteringof grain or dust at this point.

A modification of the above design is shown in Fig. 3 in which the ring8 has a somewhat different form from the groove 16. The overhanging partof the head 13 has a similar groove 17 and within their walls are anumber of balls '18, making up a ball bearing in place of the rollersshown in Figs. 1 and 2. I thus provide a joint in which there is butlittle friction and which owing to its cone hopper is adapted for usewith any of the ordinary sizes of grain spouts.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, with the track, of the loophanger, with the rollers mounted thereon to run on said track, the splitends of said loop, a ring attached thereto, the spout, the head thereofprovided with the overhanging part, and anti-friction bearings providedbetween said part and said ring, substantially as described.

2. The combination, with the track, of the loop hanger having its upperpart parallel with the track, the grooved rollers 4. mounted on saidhanger to run on said track, the ring 8 secured upon the ends of saidloop, the stud bolts arranged in said ring, the rollers 12 arranged onsaid bolts within the ring, the hopper cap or head 13 having the annulargrooved shoulder to engage said rollers, and the sheet metal portion ofthe spout attached to said cap or head, substantially as described.

3. The combination with the elevated track, of the loop hanger havingits upper portion parallel with said track, grooved rollers arrangedupon said upper portion, the studs 6 projecting from the lower portionsof said pipe extending downwardly from said head,- loop beneath saidtrack to prevent saidpulsubstantially as described. 10 leys from risingthereon, the split lower ends In testimony whereof I have hereunto setof said loop, the ring secured between the my hand this 19th day ofSeptember, 1892.
